I don't know that, but smaram is a member of bittube, he should be able to tell you if the guy on discord truly is a staff member / dev / CEO or whatever
bittube also have an official twitter (not verified yet): https://twitter.com/BitTubeApp

If you search "Dwarf" in the official Bit.Tube discord, you can read some info from the main Admin of their discord. Apparently he purchased one or more, received it, verified that it worked. Then after spending more time with it, realized it wouldn't hash for more than 20-ish minutes. He either inferred or talked to the Dwarf team directly, that they created the miners, they weren't stable, so they were selling these faulty miners to finance their next round of miners that would hopefully work. So it looks like they never intended to share these devices, but simply were selling them to cover their own costs. Why they would send faulty miners at all is beyond me. This is from the main Bit.Tube guy, but take it with a grain of salt.
